If they're batting together, they'd need 11.25 out of the 45 times. If you're counting individually for each kid, for them to both have that average, they'd need to hit 22.5 times
If the 3’s were exponents then... i got 50r3
how i solved:
39r3 + 11r3 + 45s3 - 5s3 - 40s3
50r3 + 40s3 - 40s3
50r3 + 0
= 50r3
55a and 22b both are terms in that equation
Answer:
If b is 3, x=-1
Step-by-step explanation:
-2(3x-5)=16
use distributive property
-6x+10=16
take 10 away from both sides
-6x=6
divide both sides by -6
x=-1
